To @ZZ whom, t may concern:

Be it known that I, VICTOR ANGEEEE, a citizen of the United States, anda resident of Philadelphia, Pennsylvania. have invented certainImprovements in Railroad-Frog Structures, of which the following is aspeciiication.

The object of my invention is to improve the construction ofrailroad-frogs by inserting in thefrog a hard-metal section having thepoint and the side bearing-plates all in one piece. This object I attainin the following manner, reference being had to the accompanyingdrawings, in which- Figure l is a plan view of a railroad-frog,illustrating myinvention. Fig. 2 is a section on the line 2 2, Fig. l.Fig. 3 is a section on the line 3 3, Fig. l. Fig. A is asection on theline 4 4, Fig. l. Fig. 5 is a perspective view of the hard-metalsection, and Figs. 6 and 7 are views of modifications of my invention.

A and B are rails which terminate in the point a, and A and B are therails which terminate in the wing-sections A2 and B2.

In order to prevent the rapid wearin g away of the frog-point and theedges of the wingrails opposite the point, I make these parts of hardmetal, preferably manganese steel, and in order to make a perfectlyrigid and substantial structure I make a casting D (shown clearly inFig. 5) of manganese steel or other suitable hard metal, with the pointct and cheek-pieces ct and b integral therewith. I preferably insertfilling-blocks b b between the rails A and B and the wing-rails A2 andB2, as shown clearly in Fig. 4, which overlap the joint between thepoint-section and the main rails, so as to add strength to thestructure. The edges of the casting D are shaped to conform to therails, so that they can be bolted firmly to the casting by bolts d.

It will be noticed in referring to Fig. l that the wing-rails are bentat c c to form cavities for the cheelnpieces Ct Z1', which arepreferably thick at the center and tapered toward each end of thecasting D, so that while their bearingfaces are on a line with the innerfaces of the wingrails their outer edges conform to the shape of thebent portion of the wing-rails, thus forming a very substantial frogstructure, as the bolts d d secure the several elements together.

In some instances I may find it desirable to notch the wing-railsopposite the pointsection for the reception of the hard-metalcheek-pieces, as shown in Fig. G, instead of bending the rails, or IInay partly bend the wing-rails and cut the inner face of each head awayfor the reception of the cheelepiece, as shown in Fig. 7.

The structure can be made economically and can be readily repaired whennecessary, although the hard-metal casting will usually ontlastthedrails, even though it is subjected to considerable Wear.

I claim as my inventiony In a frog structure, the combination of thesupporting wing-rails A2, B2, with a hardmetal body D, which iits intothe sides of the said supporting wing1ails and constitutes the principalpart of the frog and is formed VICTOR ANGEREB..
